Speculation was rife he could have received a fee worth hundreds of thousands of pounds, though nothing was confirmed.
Will they be financially independent?
Not completely. The Prince of Wales will also continue to offer private financial support to the couple.
This is expected to come from his £21 million a year Duchy of Cornwall income.

Will they launch their own charitable foundation?
Yes but they are not calling it a foundation. Harry andMeghan intend to "develop a new way to effect change" with a non-profit organisation, details of which have yet to be unveiled.
Will they still be able to use Sussex Royal as their brand?
No. The Queen and her senior officials have declared they must drop the use of the word 'Royal'.

Are Harry andMeghan happy about this?
The couple does not appear to be happy about this - their website states they will not use 'Royal' but argues that the monarchy has no jurisdiction over the use of the word overseas.
What will their new brand name be?
It is expected to be announced soon. They will have to change their @SussexRoyal Instagram handle. Some options are already taken - H&M is already a major clothing retailer.
Who will pay for their security?

This is causing controversy. US President Donald Trump has insisted America will not foot the bill.
A spokeswoman for the Sussexes said privately-funded security arrangements have been made and the couple will not ask the US government for help.
But it is unclear whether the private security arrangements are in addition to, or instead of, the couple's Metropolitan Police protection officers, and whether any police protection officers being used will continue to be paid for by UK taxpayers.
It is also unclear who is paying for the private arrangements - whether it is the Sussexes, the Queen or the Prince of Wales.
Neither Buckingham Palace nor the Home Office will confirm details, but the total security bill is estimated to be as much as £20 million a year.
Harry andMeghan have already left Canada, where the Royal Canadian Mounted Police said it would stop providing protection after Megxit.
What have Harry andMeghan said previously?
Their website claims it is agreed they "require effective security to protect them" because Harry was "born into the royal family" and becauseMeghan has her "own independent profile".
What about their patronages?
They will keep their royal patronages as private patronages and associations.
But Harry's military appointments will be put on hold for the next 12 months.
What about their Commonwealth roles?

Harry is quitting his role as Commonwealth Youth Ambassador.
But he will remain president of the Queen's Commonwealth Trust, andMeghan will still be the Trust's vice-president.
Where will Archie go to school?
As Archie will be spending most of his time in North America, it is likely he will not have a British education, though nothing has been confirmed.
What aboutMeghan's citizenship?
At the time of their engagement, it was announcedMeghan would be applying for British citizenship.
It is not known what stage the process was at or what will happen now.
Will they been seen again in the UK?
It is unlikely they will visit for a while with the UK and US in lockdown.
Harry was due at the London Marathon in April in a non-royal capacity, but the race has been postponed until October, and the Trooping the Colour celebrations of the Queen's official birthday in June, when Harry andMeghan could have joined the royals, will not happen in its traditional form.
Is this end of Harry andMeghan's royal roles forever?

Possibly not. The situation will be reviewed by the monarchy in 12 months' time, leaving the door open in case of a change of heart.
The Queen has told Harry the couple are much loved by the royals and would be welcomed back if they wanted to be working royals in the future.
Aren't there more pressing issues?
Exactly. The Megxit saga began before the UK was affected by the coronavirus outbreak.

Now the country is in the midst of unprecedented peacetime restrictions and dealing with the biggest public health crisis in a generation, as the world battles the pandemic.
Harry's father the Prince of Wales has tested positive for the Covid-19 illness - though he has since come out of isolation - and the 93-year-old Queen and the Duke of Edinburgh, 98, are staying at Windsor Castle for their safety.
But is Harry still in the line of succession?
Yes, he remains sixth in line and Archie is seventh in line.
